MDK stands for MIX Development Kit, and provides tools for developing
and executing, in a MIX virtual machine, MIXAL programs.
.
The MIX is Donald Knuth's mythical computer, described in the first
volume of The Art of Computer Programming, which is programmed using
MIXAL, the MIX assembly language.
.
MDK includes a MIXAL assembler (mixasm) and a MIX virtual machine
(mixvm) with a command line interface. In addition, a GTK+ GUI to
mixvm, called gmixvm, and a Guile interpreter with an embedded MIX
virtual machine called mixguile, are provided.
.
Using these interfaces, you can debug your MIXAL programs at source
code level, and read/modify the contents of all the components of the
MIX computer (including block devices, which are simulated using the
file system).
